Cleaning the charging port of your tablet or phone
It’s easy to see it as a self-contained system, but devices collect a lot of dirt. The charging port can clog and ruin the data connection or even stop you charging your device.
How to clean it? Be very, very careful! If you damage the contacts, your device may need a new port. Using a toothpick or a needle is a bad idea, unless all else fails. Use compressed air instead.
